Cracks found in either poured concrete or concrete block walls should be addressed before they get larger or start to leak outside water into the basement causing even more problems such as mold, mildew smells, and high humidity in the basement. The type of crack, whether vertical or horizontal in nature, will tell you if its a cosmetic or structural wall problem. If these cracks are not addressed, the problem will not go away, but spread further. Eco Energy Guard uses a crack injection method using a combination of polyurethanes and epoxy’s that expand deep inside the crack, filling the void and preventing any further damage or leaks. Our epoxy sealants will seal and strengthen the bond of structural cracks, so that the wall becomes one again. Don’t wait for the problem to spread and become worse.
